The delegate fight

PENNSYLVANIA: 4/22 (158 delegates)
Obama has some catching up to do to match the Clinton campaign's advantage in organization and support in Pennsylvania. 
The Clinton office was confused by a volunteer's behavior and after an Internet search determined he was an Obama volunteer. "'I was just there to check things out,' said Sam Glenzer, who oddly used his real name when signing in at the Clinton campaign office. Glenzer said he had nothing nefarious in mind." 
NORTH CAROLINA: 5/6 (115 delegates)
NBC/NJ's Carrie Dann notes an incredibly busy schedule for Bill Clinton. Today, he does a whopping seven-stop campaign blitz through western North Carolina, starting in Greensboro and working his way to liberal enclave Asheville. Along the way he'll stop in a series of towns of 40,000 or less, including Hickory. ("There are Democrats in Hickory?" jokes a local operative.) The schedule looks a lot like Clinton's daily event roster in Texas -- rapid-fire stops geared less at media markets than at the sheer volume of potential hands for the former president to shake. Any surprise that the campaign here is masterminded by Ace Smith, the engineer of Clinton's Texas win?
Asheville area superdelegate Carol Peterson will be in attendance at tomorrow's appearance by Bill Clinton. Peterson, a DNC member, has said she'll remain uncommitted through the primary. 
Hillary Clinton's visit to the state gets local coverage here, here, and here
Does Hillary Clinton know the difference between Eastern and Western Carolina BBQ? Enough that she knows it's one of the issues too controversial in the state to risk taking a side on. "I know a question not to answer," she laughed yesterday in response to the inquiry of which style she prefers. In the same interview with the Winston-Salem Journal, she denied that her husband's "other stuff" remark in Charlotte last week was "a negative comment about anyone." She also said that no one other than a president can claim experience with the kind of emergency invoked by her "3AM" ad, but that she's "been there for a lot of 3am phone calls with my husband." 
PUERTO RICO: 6/1 (55 delegates)
Since the island's primary could become important, it's worth noting that Obama's chief supporter in the territory, Gov. Anibal Acevedo Vila, was indicted "of soliciting thousands of dollars in improper contributions in exchange for favors and government contracts on the U.S. commonwealth island." Interestingly, Vila's chief lobbyist in DC is McCain strategist Charlie Black. Nothing like the small world of Washington.
